The chiller's experimental test results showed an average Specific Cooling Power (SCP) and Coefficient of Performance (COP) of 286 W/kg and 0.48, respectively. This was when the average hot water inlet temperature, cooling water inlet temperature, and chilled water inlet temperature were 83°C, 26°C and 15°C, respectively. In addition, the corresponding mass flow rates were 0.22, 0.39 and 0.09 kg/s, respectively. Despite the fact that the average SCP and COP, were rather satisfactory, analysis of experimental results conducted with different cycle times, inlet hot water temperatures, and hot water flow rates showed that a much better performance could be achieved. Experimental results indicated the following: (1) the COP increased while the SCP decreased with increased cycle time, (2) both the COP and the SCP increased with increase in heat and mass recovery time to an optimal time then started to decrease as heat and mass recovery time increased beyond the optimal time, (3) both the cooling power and COP generally increased with increase in inlet hot water temperature at a relatively higher value from 60°C to about 90°C beyond which the incremental value started diminishing, and, (4) increase in mass flow rates produced higher cooling power with decreased COP while decrease in mass flow rates of hot water produced lower cooling power with increased COP. This paper therefore recommends an adsorption/desorption time, heat and mass recovery time, inlet hot water temperature, and hot water mass flow rate of 780 s, 60 s, 83°C, and 0.22 kg/s as appropriate to give the best chiller performance for refrigeration.Authors:, RUZHU WANG, LIWEI WANG, ZISHENG LUAdvances in wind energy resource exploitation in urban environment: A review.Renewable and Sustainable Energy ReviewsWind energy continues to stand out as a more established and mature technology to offset a large proportion of power. Efforts aimed at improving wind energy use to meet the energy demand in turbulent urban wind environment have been the main technical focus. In previous studies on wind resource and behavior in urban environment, different designs of horizontal axis wind turbines (HAWTs) and vertical axis wind turbines (VAWTs) have been reviewed. This paper vividly captures the fact that wind resource has a great potential to be fully explored and developed in the urban environment. Varying ways of application and application techniques being applied for electrical generation, ventilation and pollution dispersion, onshore cooling and dehumidification of coastal urban cities, and economics and environmental benefits of applying wind energy in urban environments are summarized. Although many new ideas and solutions that factor technical, economical and environmental sustainability in urban areas are coming up every day, challenges in design are gradually being solved to take advantage of urban low and turbulent wind speed characteristics, installation space challenges, vibration and noise reduction, among others. Some of the unique solutions that have been and are being developed in the applications of wind energy technology in urban environments are also reported in this paper.Authors:, Yong Li, Wang Ruzhu, Kiplagat JeremiahBuilding and EnvironmentRadiant cooling system is a promising technique, which is suitable for independent control processes of temperature and humidity. The two main benefits of radiant cooling systems include the potential to save energy and improvement of indoor thermal comfort. However, both the poor heat transfer performance and condensation below dew point temperature restrict the widespread utilization in the residential buildings especially in humid environment. This research was focused on comprehending detailed performance of the radiant cooling panel when it used as an air conditioning system. Three radiant cooling panels with the area of 0.16 m2 were prepared for investigation and a constant temperature and humidity environment chamber employed to simulate the different indoor thermal environments. The heat transfer performance and moisture condensation phenomenon of the radiant cooling panels were investigated. The results showed that the flow state of chilled water had the biggest influence on the heat transfer performance of the radiant cooling panels. The temperature difference between chilled water and the ambient was also observed to significantly affect the performance. Condensation of moisture on the radiant cooling panels was noted to increase the heat transfer quantity, but posed a challenge in using of the radiant cooling panel. Taking the performance of heat transfer and moisture condensation into consideration, the gypsum radiant cooling panel showed the best performance as compared to the metal radiant cooling panel and pure tube panel. The radiant cooling panels can work more efficiently especially when proper control strategies are employed to avoid condensation.Authors:, Yin Yalin, , Zhai X.QInternational Journal of Heat and Mass TransferA novel composite solid desiccant material is proposed in this study to enhance thermal conductivity and
adsorption performance of silica gel. This desiccant material is fabricated by combining silica gel with
expanded natural graphite treated with sulfuric acid (ENG-TSA) as a host matrix. The performance of this
composite material with respect to different densities and different silica gel ratios was investigated.
Experimental results showed that the highest thermal conductivity of consolidated composite adsorbents
is 19.1Wm?1 K?1. This is an increase of more than 270 times as compared to that of pure silica gel. Analysis
on pore parameters demonstrated that the compression of simple mixture of ENG-TSA with silica gel
does not destroy the morphology of silica gel. In addition, both non-equilibrium and equilibrium adsorption
performance of composite silica gel and pure silica gel were evaluated. Non-equilibrium adsorption
performance indicated prominent enhancement of heat transfer, whilst equilibrium adsorption performance
indicated a reasonable mass transfer.Authors:, , Wang Liwei, , Ge TianshuJournal of EnergyIn recent years, sorption processes are increasingly gaining attention in the field of TES (thermal energy storage), owing to their advantages of high storage density and no significant heat loss during storage process. In this paper, a novel three-phase sorption cycle is proposed and evaluated for TES, to provide cold storage in summer and heat storage in winter. The uniqueness of the cycle is that it allows the solution to reach its crystallized state or even dehydrated state during the charging stage. Three working pairs, namely LiCl/H2O, CaCl2/H2O and LiBr/H2O, are considered for the proposed cycle based on their pressure–temperature-phase diagrams. Detailed analysis reveals that presence of the three-phase crystallization process could extensively improve the energy storage performance, as heat storage densities increase by 43%, 79% and 38% for LiCl/H2O, CaCl2/H2O and LiBr/H2O respectively. Overall, LiCl/H2O is determined to be the best choice among the three couples, with a cold storage density of 519 kWh/m3 (1242 Wh/kg, charged at 90 °C in summer) and a heat storage density of 618 kWh/m3 (1250 Wh/kg, charged at 75 °C in winter). This theoretical evaluation suggests that the three-phase sorption cycle can be a promising solution for TES.Authors:, Yu Nan, , Lu Zisheng, Wang LiweiIntegrated energy storage and energy upgrade, combined cooling and heating supply, and recovering waste heat with thermochemical sorption heat transformerInternational Journal of Heat and Mass TransferAuthors:, Li Tingxian, , Yan TingA review of promising candidate reactions for chemical heat storageRenewable and Sustainable Energy ReviewsAuthors:, Yan Ting, , Li Tingxian, Wang LiweiTheoretical analysis and parameter optimize of a solar hybrid one-rotor two-stage desiccant cooling and heating systemApplied Thermal EngineeringAuthors:, Zeng Dongqi, Li H., Dai Yanjun, Xie A.X.ProjectsTeam members:, TEAM SJTUA Survey on Renewable Energy Cooperation between China and AfricaTeam members:, Zhao Yanjie, Shao DandanLanguagesEnglishSwahiliChineseluhyaSkillsEnglishMicrosoft OfficeRenewable EnergyProject PlanningAutoCADEnergy EfficiencyEngineeringEnergyProject ManagementNegotiationResearchSustainabilityContract ManagementBudgetsNew Business DevelopmentBusiness DevelopmentBusiness StrategyTeachingSolar EnergyCADProcurementManufacturingPowerPointMatlabEnergy ManagementMicrosoft WordWindowsTeamworkConstruction ManagementBusiness PlanningSupervisory SkillsProject EngineeringEnvironmental AwarenessStrategic PlanningConstructionHVACMicrosoft ExcelEducationMaster's Degree, Solar powered adsorption coolingActivities and Societies:&Solar Decathlon-China, 5th National University Student Social Practice and Science Contest on Energy Saving & Emission Reduction, President of the Africans students AssociationBEIJING LANGUAGE AND CULTURE UNIVERSITYDiploma in Chinese Language and Culture, Chinese Language and CultureActivities and Societies:&Cultural DebateBachelor's Degree, ENERGY ENGINEERINGTechlab Computer and Electronic CollegeEshikulu Secondary SchoolNdabarnach Primary School
